Apparatus for manipulating and securing tissue

摘要

Apparatus for manipulating and securing tissue are described herein. In creating tissue folds within the body of a patient, a tissue manipulation assembly may generally have an elongate tubular member, an engagement member slidably dispose through the tubular member and a distal end adapted to engage tissue via a helical member, tissue stabilizing members positioned at the tubular member distal end which are adapted to stabilize tissue therebetween, and a delivery tube pivotable about the tissue stabilizer. The stabilizing members can be adapted to become angled relative to longitudinal axis of the elongate tubular member. Moreover, one or all the articulation controls and functions can be integrated into a singular handle assembly connectable to the tissue manipulation assembly via a rigid or flexible tubular body.

主权项

1. A needle deployment assembly, comprising:
an elongate flexible catheter; a control housing at a proximal end of the catheter; a needle opening at a distal end of the catheter; two or more anchor assemblies within the catheter, with each anchor assembly including a first anchor attached to a second anchor via a suture, and with the first and second anchors each having a proximal tubular collar attached to a distal tubular collar by one or more flexible elements, with the suture extending through the proximal and distal collars of the first and second anchors; with the first and second anchors temporarily interlocked via a first pair of curved tabs on the distal tubular collar of the first anchor engaged with a second pair of curved tabs on the proximal tubular collar of the second anchor; and with the first and second pairs of curved tabs adapted to interlock the first and second anchors when they are within the catheter, and to unlock the first and second anchors from each other when the first anchor is moved out of the catheter.
